What is Digicert DCV?
DigiCert DCV (Domain Control Validation) is a security scanner bot operated by Cloudflare that validates domain ownership for SSL/TLS certificate issuance. It verifies that certificate applicants have control over the domains they want to secure. Agent Analytics can track when it visits your website.

Expected Behavior
Digicert DCV's pattern depends on who pointed it at you. Continuous monitoring services check daily or even hourly, while a one time assessment sweeps once and disappears. Expect requests aimed at login pages, admin paths, APIs, and configuration files, because exposed ones are what scanners exist to find.

Disallow: /Frequently Asked Questions
Should I Block Digicert DCV?
Not unless you already run your own scanning and want cleaner logs. Digicert DCV checks websites for exposed vulnerabilities, and some scanning services report what they find to site owners for free. Almost none of the top websites we track have robots.txt rules for Digicert DCV right now.
Does Digicert DCV Respect Robots.txt?
Yes. Digicert DCV is expected to honor robots.txt rules, so a disallow rule is the right first move. Automatic Robots.txt adds and maintains that rule for you, and Agent Analytics confirms Digicert DCV actually honors it.
Does Digicert DCV Access Private Content?
It probes for private content deliberately. Login pages, admin panels, and API endpoints are exactly what Digicert DCV tests, because exposed ones are what it exists to find. Probing is not the same as getting in, but expect requests to sensitive paths in your logs.
Why Is Digicert DCV Visiting My Website?
Digicert DCV is scanning your site for vulnerabilities, either as part of a sweep across the whole internet or because someone requested an assessment of your domain. Recurring visits usually mean a monitoring service has you on its list.
How Can I Tell if Digicert DCV Is Visiting My Website?
Agent Analytics tracks Digicert DCV visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user agent string contains "Digicert DCV". Look for probes of login, admin, and API paths. Keep in mind that Digicert DCV doesn't publish a verification method, so any client can claim its user agent string and a log match is a hint rather than proof.
